Technical Field

[0001] This utility model relates to the field of composite new material processing, and in particular to a stirring paddle type mixing device for the production of composite new materials. Background Technology

[0002] In the field of composite new material processing, the uniformity and efficiency of raw material mixing directly determine the performance and quality of the final product. Therefore, as the core equipment in the production process, the design rationality and operational stability of the mixing device have attracted much attention from the industry.

[0003] With its simple structure, convenient operation, and strong adaptability, the agitator-type mixing device has become a widely used type of equipment in the production of composite new materials. It uses agitation components to mechanically stir various raw materials to achieve the mixing of different components, laying the foundation for subsequent molding, processing and other processes.

[0004] However, conventional paddle-type mixing devices still have shortcomings in practical use and need to be improved.

[0005] Most devices' mixing components can only achieve single-dimensional rotational mixing, and the movement trajectory of the mixing blades is fixed, which easily leads to the formation of stratification of raw materials in the mixing tank. This is especially true for composite new material raw materials with large density differences and irregular particle shapes, which are prone to local uneven mixing problems, directly affecting the subsequent use of the material. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a stirring paddle type mixing device for the production of composite new materials. It aims to improve the problems in the prior art where the stirring blade can only rotate in one dimension and the stirring blade trajectory is fixed, which easily leads to the stratification of raw materials and local uneven mixing for raw materials with large density differences and irregular particles, thus affecting the subsequent use of the materials.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a mixing paddle type mixing device for the production of composite new materials, comprising a support frame, a support leg fixedly connected to the lower surface of the support frame, a mixing barrel rotatably mounted on the inner surface of the support frame, a support plate fixedly connected to the upper surface of the support frame, a mixing assembly provided on the outer wall of the support plate, a feed pipe penetrating and fixedly connected to the lower surface of the mixing barrel, and a support assembly provided on the lower surface of the mixing barrel;

[0008] The stirring assembly includes a rotating shaft that is rotatably connected to the inner surface of a support plate. A motor is mounted on the lower surface of the support frame. A pulley is fixedly connected to the top of the outer wall of the rotating shaft. A pulley is connected to the outer wall of the pulley via a belt drive. A rotating rod is slidably connected to the inner surface of the pulley. A stirring shaft is slidably connected to the lower half of the outer wall of the rotating rod. A guide groove is provided at the top of the outer wall of the stirring shaft. A fixing block is fixedly connected to the lower surface of the support plate. An extrusion member is fixedly connected to the bottom of the right surface of the fixing block.

[0010] The support assembly includes a chute, which is formed at the bottom of the inner surface of the support frame. A connecting block is slidably connected to the inner wall of the chute. A connecting seat is fixedly connected to the lower surface of the connecting block. A ball bearing is provided through the lower surface of the connecting seat. A toothed groove is formed on the outer wall of the mixing tank. A gear is fixedly connected to the outer wall of the rotating shaft.

[0011] As a further description of the above technical solution:

[0012] The rotating shaft passes through and is rotatably connected to the inner surface of the support frame, and the bottom end of the rotating shaft is fixedly connected to the output shaft of the motor.

[0013] As a further description of the above technical solution:

[0014] The rotating rod passes through and is rotatably connected to the inner surface of the support plate.

[0015] As a further description of the above technical solution:

[0021] As a further description of the above technical solution:

[0022] The gears and tooth grooves mesh.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, through the cooperation of the stirring components, the motor drives the rotating shaft to drive pulley one, pulley two and rotating rod to rotate. While the stirring shaft rotates, the extruder squeezes the guide groove to make the stirring shaft move up and down reciprocatingly. This drives the stirring blade to both rotate and tumble the raw materials up and down, avoiding the stratification problem caused by one-dimensional stirring, improving the mixing uniformity and ensuring the subsequent performance of the composite new material.

[0025] 2. In this utility model, through the linkage between the support component and the stirring component, the rotating shaft drives the gear meshing groove to make the stirring tank rotate in the opposite direction. The ball bearing reduces the friction of the stirring tank rotation to ensure stable operation. The opposite movement of the stirring tank and the stirring blade further enhances the mixing effect. In addition, the inclined design of the bottom of the inner wall of the stirring tank facilitates the collection and discharge of raw materials, taking into account both mixing efficiency and discharge convenience, and improving the practicality of the device.

The bottom of the inner wall of the mixing tank 3 is designed to be low in the middle and high around the edges to facilitate guiding the mixed raw materials for the production of composite new materials. A support assembly is provided on the lower surface of the mixing tank 3.

[0035] Reference Figures 1-3 The stirring assembly includes a rotating shaft 52, which passes through and is rotatably connected to the inner surface of the support plate 4. The rotating shaft 52 is located on the left side of the inner surface of the support plate 4. A motor 51 is installed on the lower surface of the support frame 1. The motor 51 is existing technology and can be implemented by those skilled in the art. As it is existing technology, it will not be described in detail in this case. A pulley 53 is fixedly connected to the top of the outer wall of the rotating shaft 52. A pulley 55 is connected to the outer wall of the pulley 53 via a belt 54. Both the outer walls of the pulley 53 and the pulley 55 have recesses. The inner surface of belt 54 is provided with protrusions, and the protrusions and recesses mesh to ensure stable transmission. The inner surface of pulley 55 is penetrated and fixedly connected to a rotating rod 56. The lower half of the outer wall of the rotating rod 56 is slidably connected to a stirring shaft 57. The rotating rod 56 and the stirring shaft 57 will rotate synchronously. The lower half of the outer wall of the stirring shaft 57 is fixed with stirring blades. The top of the outer wall of the stirring shaft 57 is provided with a guide groove 510. The lower surface of the support plate 4 is fixedly connected to a fixing block 58. The bottom of the right surface of the fixing block 58 is fixedly connected to an extruder 59. The guide groove 510 and the extruder 59 fit together.

[0036] Reference Figures 1-3The rotating shaft 52 is rotatably connected to the inner surface of the support frame 1. The bottom end of the rotating shaft 52 is fixedly connected to the output shaft of the motor 51. The motor 51 can drive the rotating shaft 52 to rotate. The rotating rod 56 is rotatably connected to the inner surface of the support plate 4. The support plate 4 provides support for the rotating rod 56. The extrusion member 59 is slidably connected to the inner wall of the guide groove 510. The guide groove 510 is set to a closed annular shape with the left side higher than the right side. When the stirring shaft 57 rotates, the guide groove 510 will be squeezed by the extrusion member 59, which will drive the stirring shaft 57 to move up and down reciprocally to achieve the up and down stirring effect.

[0037] Reference Figure 2 , Figure 4 , Figure 5 The support assembly includes a slide 71, which is annular and located at the bottom of the inner surface of the support frame 1. A connecting block 72 is slidably connected to the inner wall of the slide 71, and a connecting seat 73 is fixedly connected to the lower surface of the connecting block 72. A ball bearing 74 is provided through the lower surface of the connecting seat 73, which provides support for the mixing tank 3. A toothed groove 76 is provided on the outer wall of the mixing tank 3, and a gear 75 is fixedly connected to the outer wall of the rotating shaft 52.

[0038] Reference Figure 2 , Figure 4 , Figure 5 The connecting block 72 is fixedly connected to the lower surface of the mixing tank 3. The centers of the support frame 1, the mixing tank 3, and the slide 71 are on the same axis. The ball 74 is set as "spherical". The center of the ball 74 is always located inside the connecting seat 73. The contact surfaces of the ball 74 and the connecting seat 73 are in contact. The ball 74 can reduce the friction during rotation. The ball 74 rolls on the inner wall of the slide 71. The gear 75 and the tooth groove 76 mesh. When the gear 75 rotates, it will drive the mixing tank 3 to rotate in the opposite direction.

[0039] Working principle: First, the raw materials for the production of the composite new material to be mixed are put into the mixing tank 3 through the top opening. Then, the motor 51 is started to drive the rotating shaft 52 to rotate. When the rotating shaft 52 rotates, it will drive the pulley 1 53 to rotate synchronously. The pulley 1 53 transmits power to the pulley 2 55 through the belt 54 meshing on the outer wall, so that the pulley 2 55 rotates synchronously, which in turn drives the rotating rod 56 and the stirring shaft 57 to rotate. The stirring blades on the lower half of the outer wall of the stirring shaft 57 begin to rotate and stir the raw materials in the mixing tank 3.

[0040] Meanwhile, during the rotation of the stirring shaft 57, the extruder 59 exerts a squeezing force on the inner wall of the guide groove 510, forcing the stirring shaft 57 to reciprocate up and down along the axis of the rotating rod 56, thereby driving the stirring blades to tumble the raw materials up and down while rotating and stirring, thus improving the uniformity of mixing.

[0041] When the rotating shaft 52 rotates, the gear 75 fixedly connected to its outer wall rotates synchronously. Because the gear 75 meshes with the toothed groove 76 opened on the outer wall of the mixing tank 3, the mixing tank 3 will rotate in the opposite direction. Through the opposite movement of the mixing tank 3 and the mixing blade, the mixing effect of the raw materials is further enhanced.

[0042] When the mixture is ready, turn off the motor 51 and open the valve in the middle section of the discharge pipe 6. The mixed raw materials will converge towards the center along the bottom of the inner wall of the mixing tank 3 under the action of gravity, and finally be discharged from the discharge pipe 6. Collect the discharged mixed raw materials to complete the mixing operation.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
